Title:
GLASS-COATED ALUMINUM NITRIDE PARTICLES, METHOD FOR PRODUCING SAME, AND HEAT DISSIPATING RESIN COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2019/124147
Kind Code:
A1
Abstract:
Achieved are: glass-coated aluminum nitride particles which enable improvement of moisture resistance, while maintaining high thermal conductivity; and a method for producing the glass-coated aluminum nitride particles. Glass-coated aluminum nitride particles according to the present invention comprise aluminum nitride particles and a glass phase which covers at least a part of the surface of each aluminum nitride particle. The glass phase is a composition which contains at least a glass component; and the proportion of the composition containing a glass component is from 0.1 part by mass to 5.0 parts by mass relative to 100 parts by mass of the aluminum nitride particles; and the aluminum nitride particles have a volume cumulative d50 of from 10 μm to 200 μm.
